Title:
  Upgrade from 20.04 to 22.04 failed with "Fatal: unexpected error from
  getentropy: Invalid argument"

Status in apt package in Ubuntu:
  Confirmed

Bug description:
  Upgrade from 20.04 to 22.04 failed with "Fatal: unexpected error from
  getentropy: Invalid argument". We have fips-updates enabled thru
  Ubuntu pro subscription. Tried to upgrade from 18.04 to 22.04. Upgrade
  from 18.04 to 204 is successful but upgrade from 20.04 to 22.04
  failed. Apt or do-release-upgrade commands no longer working after the
  upgrade failed so we have to restore the host to the Ubuntu 20.04
  snapshots.
